Experimental Information:

X-RAY DIFFRACTION

Space Group:

H 3

Cell Constants:

a = 43.1   b = 43.1   c = 59.4 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the X-PLOR 3.0 program. The R value is 0.156 for 1775 reflections in the resolution range 10.0 to 2.2 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
